IMPROVEMENT IN DRAUGHT-ATTACHMENT.

(1th gtlgrmzlr harm in in the: inter fitment animating gut in its arms.

To ALL WHOMIT MAY CONCERN:

Be it known that I, MOSES ADSIT, of Forrest, in the county of Clinton,and State of New'Yor-k, have invented a new and improvedDraught-Attachment for vehicles; and I do hereby declare that thefollowingis a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the same,reference-being had to the accompanying drawings, forming part of thisspecification. I i

This invention relates'to a new and useful improvement indraught-attachments for all kinds of vehicles which are drawn by horses,and has for its object the equalizing of the draught, by admitting ofthe whifile-trees being automatically adjusted in relation with thedouble-tree under pull of the team, and in such a manner that if onehorse of a team has an inclination to pull more than his share, hislabor will be proportionably increased, while the other horse willhave'his labor correspondingly decreased, and will feel encouraged toexert himself 'and pull up even with the more ambitious one. 7

By this means} the device will not only have a tendency-to correct ateam which pulls unevenly for the time edge of the same, as shown infig. 2.

being, but will also have a tendency to break or train an unmatchedteam, so that the two horses of the same will in a short time bepermanently matched, so far as equal draught is concerned. In theaccompanying sheet of drawings w m Figure 1 is a plan or top view of myinvention. Figure 2, a section of the same taken in the line at a,fig. 1. Similar-letters of reference indicate corresponding parts. A.represents a draught-pole, which does not require any peculiarity in itsconstruction, and B is a doubletree, secured to the draught-pole bybelt, a, which passes through the front end of a metal strap, 0, therear part of which is bolted ,to the draught-pole, andis bent upward, soas to extend over the double-tree, to the front This double-tree'isconstructed 'ina peculiar manner as follows: To thercar side of the samethere is attached a metal bar, D, the ends of which are hent'around theends of the double-tree, and firmly bolted thereto, agroove or rebatebeing made in the upper and lower surfaces of the double-tree to receiveplates 6 6, which are somewhat shoiter than the double-tree, in orderthat the latter'may have a certain degree of longitudinal playindependently of them.

To the ends of these platesb b clevises E E are attached, the 'boltsc ofwhich pass down through oblong slots, (2, in the whifile-tree, to admitof the independent play of the-double-tree, and at the same timeallowing said bolts to connect the two plates. The whiihc-trees to whichthe horses are attached are connected to these clevises.

The strap C has abolt, a, passing through it, which extends throughanoblong slot,'f, in the double-tree,

and also through the two plates 6 b and into the draught-poleA, (seefig. 2.) The oblong slotf, like the slots 11 of the'bolts a, admits ofthe independent play of the doublb-tree, while the bolt'e forms apositive connection between the plates 6 and the strap. v t

This arrangement admits of the clevises E being thrown respectivelyfurther from and nearer to the bolt a of thedonble-tree, as the latteris moved from a right-angular position relatively with the draught-pole,the clevis at the forward end of the double-tree being brought nearerthe draught-pole than the opposite end, and the leverage power of theforward end proportionably decreased. Hence the most ambitioushorsewill, in consequence of the increased draught or labor put upon himby this automatic arrangement, check himself, while the less ambitionsone, in consequence of the decreased labor, will be stimulated to pullahead.

Strictly speaking, this automatic adjustment of the whifile trees is dueto the turning-movement of the double-tree, the plates 6 in realityhaving no longitudinal Inovementin themselves, as they are connected bythe bolt e to strap 0, and can swing or turn with the double-tree, butnot being positively connected with it, or not turning from the samebolt a as a centre, (e being the bolt of the plates 5,) the resultspecified is obtained.

I would remark that the bolts which pass through the double-tree mayheprovided with friction-rollers, in order to avoid'friction in theworking of the device.

I claim as new, and desire to secure by Letters Patent- The plates 6 b,sliding in grooves upon the top and bottom of the double-tree B in frontof the band D, said plates 6 secured together at their ends and centresby the bolts 0 a, which slide in the slots df of tllddouhle-trfl,

all constructed and arranged toopei'ate as herein described for thepurpose specified:

MOSES ADSIT.
